you must trust me. tavis: first of all, good to see you again. about this project -- i have been reading so much lately about how, into the future, whirs will continue to be fought, sadly. more and more, we are going to fight over is not religion, not geography, who has the right to decide the line. we are going to be fighting over water. >> it is a sustainable item. tavis: who controls the water sources? into the fray comes this wonderful project, "a dark truth." i will let you explain the character you play, then i want to get into the film. so many real-life issues run through this movie. i want to bounce back and forth, if i can.
